Mueller Co (www.muellercompany.com), a manufacturer of water and natural gas distribution products, marked its 150th Anniversary at the American Water Works Association Annual Conference and Exhibition in Toronto. The ceremony featured a presentation of a plaque and letter sent on behalf of Illinois State Governor, Rod Blagojevich. Mueller, which was founded in Decatur, Ill. in 1857, was cited in the governor’s letter for its promotion of the State of Illinois in world commerce and the company’s significant contribution to the state’s economy.
